Re: Liquid Rosin Flux
Re the grades of rosin flux, I'm not sure what I'm using, most likely RMA. It was being thrown out of Stores 25 years ago for exceeding the use by date, I can only read "Ersin Multicore Rosin Flux Type 5381 1L" so I have several lifetime's supply. We later used a pale blue water-based flux which left no residue and was slightly more 'activated'. This was brilliant and if I had to buy flux now I'd look for something similar - but beware, most are corrosive and for plumbing or soldering steel or stainless. The clue seems to be to look for rosin-free, halide-free, Lead Free
